Hi guys, I’ve got these 2 belemnites from the sinemurian of Lyme Regis and I was wondering whether it would be possible to put a name on them, thanks 1. 2.

Some samples of the Sinemurian stage of the Jurassic period
Svetlana posted a topic in Member Collections
Hello all. After a long break, I would like to show some examples of the Sinemurian Jurassic from my collection. The Sinemurian Stage (Sinemur) is a stratigraphic subsection, the second from the bottom stage of the lower section of the Jurassic system of the Mesozoic era. Covers time from 199.3 ± 0.3 Ma to 190.8 ± 1.0 Ma. As far as I know, these fossils are not very widespread. Arietites (Coroniceras)?.. I am not sure about these ammonites- 8 replies

Lyme Regis plesiosaur propodial with pyrite disease - how to treat
pachy-pleuro-whatnot-odon posted a topic in Fossil Preparation
Hi all, A couple of years ago I acquired a lovely pair of plesiosaur propodial bones from Lyme Regis. It was a matched pair of both humerus and femur. Today, when I was looking to make space in my cabinet for a new acquisition I had made, I discovered some odd dust next to the humerus that, on inspection and to my horror turned out to be pyrite bloom! I immediately removed the specimen from the cabinet, checked the other podial and nearby fossils, and used a tooth brush to brush of the most direct traces of pyrite decay. But the question is: what now? How do I ensure the propodial's prese -

Fossil hunting trip to Tontelange (Jurassic of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
On saturday I went on my first fossil hunting trip of 2021 with the BVP. Normally we would visit my favorite quarry "the Romontbos quarry" in Eben-Emael which is Maastrichtian in age, but due some complications that trip has been posponed till the end of September. Instead we went to the SETIM quarry in Tontelange in Belgian Luxembourg which was quite cool as it supposedly only the 2nd that this quarry allowed fossil hunting so everyone was quite excited. The rocks we hunted in this quarry are Jurassic in age, mainly Hettangian & Sinemurian. The lower levels of the quarr- 13 replies

The largest ammonite has a diameter of 3cm. The block measures 12x7x5cm. These blocks are often cut and polished, hence the name "marble". obtusum zone Marston Magna Marble Sinemurian Early Jurassic Found at Marston Magna, Somerset, England -
This ammonite was found in association with Tmaegoceras nudaries and Coroniceras luningense, indicative of the Mullerense Subzone of the Involutum Zone of the early Sinemurian. The venter is compressed and rounded on early whorls but becomes subquadrate on the outermost preserved whorl, with the strong ribs extending completely over it. Any suggestions as to its genus are most welcome!

Hi everyone, I found this ammonite recently on the beach between Lyme Regis and Charmouth in England and was hoping someone might be able to tell me what species or genus this is? It is from the Charmouth Mudstone Formation, and is about 190 million years old. If additional photos are required i can get more. The diameter of the ammonite is approx. 6 cm. Thank you!

This time it was a large Arietites solarium from the Early Jurassic Sinemurian with a diameter of 60cm. which my friend brought to me. Here's what it looked like towards the beginning of the prep. I had just trimmed off the matrix around the edges and moved on into the whorls a bit with a club hammer and pointed chisel beforehand. I had marked the point with a red line where I figured that the ribs would probably not be there any more and asked him if I should carry on nevertheless and do some carving to finish it off. He agreed, so I carried on. The matrix on these pi

Hi everyone, I have recently acquired this Xipheroceras from an old collection... it comes from the upper sinemurian of Burgundy in France. The genus Xipheroceras is easily recognisable by its spines on the edge of the whorls but would you have any idea for the species? I have not found much information for the moment.. there is Xipheroceras ziphus, trimodum, drudrieseri but I have no idea of which it could be and if these are the only species I know but there are maybe more... thanks in advance for your help!

Recently I wasnt very active here but I managed to find a couple fossils in the meanwhile. A week ago I planned to visit the Pliensbach near Holzmaden in Germany. The Pliensbach is a type locality for the so called Pliensbachium, a time period in the lower Jurassic. On the way I saw an old pile with some jurassic rocks and stopped there. Luckily I was able to find some fossils there! Here is a picture of the view I had on the top of the pile: Belemnites are very common there but I found two really nice and big ones. Both are about 15 cm long and they
